ISAAC) s. wrnson, OF WALDO, mrssouei- IMPROVEMENT IN COMBINED STACK ANDFEED'CUTTERS.

Specification forming part of Letters Patent No. 172,814, dated January25, 1876; application filed I August 19, 1875.

To all whom it may concern:

Be it known that I, ISAAC S. WILSON, of Waldo, in the'county of Websterand State of Missouri, have" invented certain newand useful Improvementsin Combined Stack and Feed Gutters and 1 do hereby declare that thefollowing is a full, clear, and exact description thereof, which willenable others skilled in the art to which it pertains to make and usethe same, reference being bad to the accom panying drawing, and to theletters of reference marked thereon, which form a part of thisspecification, and'in which- Figure 1 isa side elevation of my improvedstack-cutter. Fig, 2 is a perspective view of the same used as afeed-cutter, and attached to the cutting-box; and Fig. 3 is a bottomview of the cutter, partly in section.

Similar letters of reference indicate corresponding parts in all thefigures.

This invention consists in the construction and arrangement of parts ofa stack cutter in such a manner that it may be used as a feed-cutteralso, so that one implement shall serve the double purpose of cuttingthe stack in the field, preparatory to removing a portion of thehayor'straw, and afterward 'comminute the hay or straw thus cut off forfeed.

In the drawing, A represents the frame or handle, whicheonsists of theslotted part A and the adjustable handle A. \Vithin the slot in A ispivoted the bent lever B, which has, on the under side B, a series ofteeth or notches, b, forming a'segmental rack,that engages with a seriesof corresponding notches, c, in the back of the knife 0. The latter isaffixed, by a thinrod or wire, (1, to the spring D, which is firmlysecured in the bend of the lever B.

The other end of the knife 0 forms two arms or projections, e e, thatslide upon a.

pulley, f, Within the frame A, as shown.

The cutting-edge of the knife or cutter O f engages with and worksagainst the pointed as such, will be readily understood from theforegoing description.

The knife being lifted by raising the handle A, the point X of tongue Eis inserted into the stack at any convenient point, and by opcrating thelever B this is readily cut through,

the cutter being worked slowly through the under the cutter G, thetongue E having been previously detached from frame A, so that thestrawto be cut is grasped between the hooks f andthe cutter O.

When it is desired to use this device as a feed-cutter it is securedonto the end of the feed-box G by screws or bolts 9, as shown in Fig. 2,in such a manner that the knife 0, when operated by the lever B, willcut transversely through the feed contained in the box as it is movedalong. When used in this capacity I prefer to detach the long handle A.

Having thus described my invention, I claim and desire to secure byLetters Patent of the United States l. The combined stack-cutter hereinshown and described, consisting of the handle A, frame A, tongue E,knife 0, bent lever B B,

rod (1, and spring D, all combined and operatin g substantially as andfor the purpose hereinbefore set forth.

2. In combination with the frame A, bent lever B B, and cutter G, theanchors F, pivoted to A, and having hooks or catches f, substantially asand for the purpose herein set forth.

3. The combination of my improved stackcutter, herein. described, with afeed or cutting box, G, so as to be used as a feed-cutter, substantiallyas and for the purposes herein set forth and specified.

In testimony that I claim the foregoing as my own I have'aftixed mysignature in presence of two Witnesses.
